PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery having high capacity and excellent cycle reversibility by maximizing the large capacity of amorphous carbon and low-crystalline carbon. A 100 parts by weight of the carbon material and having an irreversible capacity general formula Li 3-X M X N ( M: Co, Ni, at least one selected from the group consisting of Mn and Cu, 0. 2 ≦ X ≦ 0.8) lithium-containing composite nitride 2 By including 0 to 150 parts by weight of the negative electrode, the irreversible capacity of the carbon material is compensated for by the nitride. |
